I’m going to have a hard time ever eating any other kind of grilled cheese sandwich after devouring these mushroom grilled cheese sandwiches. They are incredible. Creamy, gooey cheese. And the best part, sauteed, earthy mushrooms. Absolutely fantastic.
It takes a bit of time to make these sandwiches. You can’t rush it since you want the onions to be soft and golden. Remember that you want the cheese to be melted and you just can’t rush that. Your efforts will be rewarded.
I like to cook these mushroom grilled cheese sandwiches on my Cuisinart Griddler. It does sandwiches like nobody’s business.
